UK-Developed 'DNA Spray' Marks Dutch Thieves With Trackable Water
eldavojohn writes "In Rotterdam, there's a new technology in place that dispenses a barely visible mist over those around it and alerts the police. The purpose? To tag robbers and link them back to the scene of the crime. From the article, 'The mist — visible only under ultraviolet light — carries DNA markers particular to the location, enabling the police to match the burglar with the place burgled. Now, a sign on the front door of the McDonald's prominently warns potential thieves of the spray's presence: "You Steal, You're Marked."' Developed in Britain, it's yet to nab a criminal but it will be interesting to see whether or not synthesized DNA will hold up as sufficient evidence in an actual court of law." So it's not just for copper thieves.
"The police acknowledge that they have yet to make an arrest based on the DNA mist, which was developed in Britain by two brothers, one a policeman and the other a chemist. But they credit its presence — and signs posted prominently warning of its use — for what they call a precipitous decline in crime rates (though they could not provide actual figures to back that up).
I don't see any burglars, so it has to be working.
Of everything. Because this is a fine mist that will stick to everything, even your hands, shoes, clothes, socks, the bag, the tools, the stolen property. So you'd need to do a job and then ditch everything you have in a forensically secure way. I've used a similar competing product called SmartWater.
The beauty of things like SmartWater is that its a suspension of fine molecules that can be *uniquely* identified to a particular user (i.e. you get a coded bottle with a unique number and a unique solution). The UV is just there to light up when people go through police stations but the chemical itself is, supposedly, uniquely identifiable.
Answering "How did you come to have UV marker solution on your clothes?" is easy. You were security marking your own equipment, you work with the stuff all the time, it must have been on something you picked up, maybe someone was playing a prank. Answering "How did you come to have a UV marker solution on the clothes you wore last night that is ONLY issued to Company X, when there was a burglary at Company X last night, when you claim to have been at home and never near Company X?" is a bit more tricky, especially if it's a fine mist that soaks into anything and everything it touches.
I've used the SmartWater stuff, which is very similar to this, and it's a wonderful deterrent. They claim to have a 100% conviction rate when property / people are found by police with SmartWater on them and given that they are often used in bank security vans, that's quite impressive. I don't know if that was true, or still is, but it's plausible. Basically if the police find the tiniest forensic trace of that stuff on property / people they question, they can take a sample, send it to the company, who will tell them who bought that EXACT pot of tracer ink. I also know from experience that a 50ml pot of SmartWater is enough to chemically mark every PC or electrical item in a school several times a year and last several years.
This stuff isn't just a UV-tracer. It puts you, forensically, at the exact scene of a particular crime. And given that I know of no lawsuits with any of these stuff being in question, they must have a pretty cast-iron chemical description that can satisfy a court of law or, at least, people who are caught with it on their clothes that it wouldn't be worth challenging.
It's also very good for equipment recovery. It basically guarantees identificiation / return of stolen property if it comes into police hands. Before, even if your stuff was security marked, it wasn't guaranteed that you would get it back (the first thing is that people try to file off the security marks - I've had police tell me of cases where they had to return goods with obviously filed-off security marks because they couldn't prove it WASN'T the suspected thieves and couldn't trace the actual owner), but with SmartWater once it's in police possession even the smallest tiny speck of SmartWater (which can be deployed even on hard-to-cleanse areas like across the PCB's of (unpowered) motherboards) or similar will link it to it's owner.
Actually I'd expect it to be even worse, thanks to the CSI effect. Basically the same blind belief that if it's some hi-tech shit, then it's more infallible than the Pope and those scientists 100% thought of and prevented every possible problem or false positive, that you can see in the GP post.
Someone _will_ get sent to jail by some idiot jury because the real burglar -- who, for example, is an employee and didn't even need to synthetise anything: he just nicked the bottle that the PHB cleverly hid in his desk drawer -- sprayed them with it.
That's actually the important part: often when it looks like there's some impossible hurdle like synthetising DNA, there are often _much_ simpler ways to plant it, _and_ you can rely on some idiots still thinking that only the really complicated way exists. E.g., people have already planted DNA at a crime scene by just taking a cigarette butt from a bus station and dropping it there. Here you don't even have to do that.
Or as an even more trivial example, if a co-worker you really don't like leaves his coat behind and his wallet in it, spray the coat and banknotes in the wallet, steal the same amount from the cash register, tip someone off that you saw them stealing again. Double profit. You got the money, and got rid of that guy or gal you don't like.
Yeah, they'll end up having to convince a jury that those scientists and their hi-tech solution are fallible after all. Good luck with that in a world being told the opposite by PR. And where they saw on TV every week that you can take a hair you found on a carpet and know exactly that it belongs to the killer (and not, say, to one of the guests the victim had two days before that, or some guy in the bus leaving hair on her coat) and run a DNA analysis to tell you exactly what the killer looks like. Or that you can take a two by two pixel image of the back of someone's head from a security camera, enhance it to a clear 1600x1200 image and, with a couple more mouse clicks, turn it around to see the culprit's face.
Seriously, we're already at the point where some juries acquit because you didn't do that, or conversely people who spent time on the death row because some pseudo-science mumbo-jumbo must be 100% correct and accurate like on CSI.

""How did you come to have a UV marker solution on the clothes you wore last night that is ONLY issued to Company X"
Are you sure it was only issued to company X? Show my evidence that no other bottle could possibly contain the same solution. See, with humans this process occurs naturally, everyone has different DNA (with extremely high probability) because of how biology works. Once you start making your own, you've shown that it's possible to duplicate DNA, thus the solution is NOT necessarily unique.
"I also know from experience that a 50ml pot of SmartWater is enough to chemically mark every PC or electrical item in a school several times a year and last several years."
So, you have now just told us that you have the ability to put the SAME SOLUTION on multiple DIFFERENT ENTITIES MULTIPLE TIMES PER YER for years on end. Thus, anyone could, with only a tiny amount of this stuff, frame any number of different people with extreme ease.
"but with SmartWater once it's in police possession even the smallest tiny speck of SmartWater (which can be deployed even on hard-to-cleanse areas like across the PCB's of (unpowered) motherboards) or similar will link it to it's owner."
No, it will link it to whoever managed to get their hands on one of these bottles and spray it on whatever the fuck they felt like. I could go mark every computer at my local university with this stuff and then claim that the entire computer lab belonged to me because only I have this bottle of magic property-identifying liquid.

I would guess, the product in question is http://smartwater.com/
Living in the UK a few years back, I had started using it to mark belongings of mine, after a friend working for the police recommended it.
The stuff is almost transparent - but, when I applied it to a grey camera lens - it's still easily visible on it -- on black or white lenses it's not much of a problem.
On the greyish lens, I tried to wash it off - and have found that I couldn't (wet wipes, ...).
The stuff sticks fairly well - I can't even say I managed to get a noticable amount of it off.
As far as marking belongings goes - you literally only need a very small spot of it; and you can pick some place where it isn't too obvious. On my Nikon lenses, I sometimes put the spot on the 'o' in the Nikon logo. Trying to get this off would probably seriously (cosmetically) harm the lens; scratch off part of the logo - and the resale value will drop massively: No point trying to call it 'near mint condition' afterwards.
Under UV light, the spot is easily visible - under normal light, it's near invisible.
From another friend who works as a shop fitter for jewellers, he's tried it in alarm systems, and he told me, that it will take a few days/weeks before you get all of it off (i.e. small amounts still lodged in skin pores are almost impossible to get out easily).
This shit doesn't contain "DNA," it contains a chemical sequence that's sufficiently unique. They say "DNA" because DNA is so variant no two people who aren't clones (such as twins) have the same DNA. But it catches idiots with buzzwords.
